Predicted to enable phosphatidylinositol-3,5-bisphosphate phosphatase activity and phosphatidylinositol-3-phosphatase activity. Predicted to be involved in phosphatidylinositol dephosphorylation. Predicted to be located in several cellular components, including endoplasmic reticulum-Golgi intermediate compartment; perinuclear region of cytoplasm; and ruffle membrane. Predicted to be active in cytoplasm; membrane; and nuclear envelope. Orthologous to human MTMR6 (myotubularin related protein 6). [provided by Alliance of Genome Resources, Apr 2022]
